What changes occured through 1960-1970

The 1950s in America are often described as a time of complacency. By contrast, the 1960s and 1970s were a time of great change. New nations emerged around the world, insurgent movements sought to overthrow existing governments, established countries grew to become economic powerhouses that rivaled the United States, and economic relationships came to predominate in a world that increasingly recognized military might could not be the only means of growth and expansion.
